The problem isn't just higher frequencies, which as you say getting to optical frequencies will be really hard, but not impossible. The rest of the problem is bandwidth. I can't find the source article for this, but I'd bet the bandwidth is tiny. Visible light covers and entire octave of bandwidth. I've seen zero sign that metamaterials will ever have close to that much bandwidth. Increasing the frequency just means making things smaller. Most of the metamaterials have elements that resonate at specific frequencies.

I don't know what stone tablets have to do with a Finite State Machine, but I'm no FSM heretic; my programs always transition cleanly from one state to the next, with no muddled undefined states in between.

And I'm pretty sure Moses cleanly transitioned to his final state as well.

Questions remain as to whether the opening of the platform, slated for later this year, will be through Dashboard-like Widgets or a separate SDK."

Explore your brain, literally, at the largest online atlast of the brain! BrainMaps.org features the highest resolution whole-brain atlases ever constructed, with over 50 terabytes of brain image data directly accessible online. Users can explore the brains of humans and a variety of other species at an unprecedented level of detail, from a broad view of the brain to the fine details of nerves and connections. The website also includes a suite of free, downloadable tools for navigating and analyzing brain data.
The high-resolution maps will enable researchers to use "virtual microscopy" to compare healthy brains with others, looking at structure, gene expression and the distribution of different proteins. They will enable better understanding of the organization of normal brains, and could help researchers in identifying fine morphological and chemical abnormalities underlying Alzheimer's, Parkinson's and other neurological diseases."
